Patent DE-2607932-A1 (DE)
Title: Mixer with annular mixing chamber for building materials - with central gear motor for counter-rotating tool assemblies
Inventor: HAMMANN HEINZ
IPC: B28C5/16
Filed: 1976-02-27
Abstract: Mixing machine comprises an annular mixing chamber, and counter-rotating pool assemblies for mixing building materials and other granular and liq. materials. The tool assemblies are driven by means of a central vertical motor shaft, gears and ring gear.

Title: Energy optimised regulator for heat exchanger - has automatic adjustment effected by matching exchange level and vols. of exchange media
Inventor: BRETTING EKKEHARD B DIPL ING
IPC: F25B49/02
Filed: 1976-03-19
Abstract: The energy optimised regulation of the connecting system of heat exchanges and the remaining parts of a circulating process is for regulating water re-cooling systems in connection with refrigeration systems. The automatic adjustment of the most favourable operating condition for the heat exchanges is effected by the matching of exchange level and volumes of exchanging media. By variation of the temp. level of the heat exchanger and by variation of the water and air volumes, the most favourable operating condition is so set up that the lowest possible energy for the total system is used.

Patent DE-2622930-A1 (DE)
Title: Gasification plant for solid waste fuel - has redirected gas flow path to prevent formation of tar deposits in plant and mixes gases
IPC: F23G7/10
Filed: 1976-05-21
Abstract: Arrangement for treating of stored fuel used for gas generation. The hydrocarbons in the gas tend to condense and form tarry precipitates. The arrangement prevents formation of these deposits which affect the performance of the gas generator. Gas is generated from a variety of fuel such as agricultural and forestry waste. The fuel in the plant moves vertically downwards corresponding to the time rate of the thermal conversion. The downwards movement is converted also into a predominantly horizontal centripetal movement. The thermal conversion products are generated by the gasification or by the dry distillation of the fuel. These gasification processes as well as partial combustion is promoted by supply of oxygen in the air. Gaseous products are mixed and joined to form a single gas stream.

Title: Continuous albumin concentrate prodn. from aq. solns. - by sterilising freezing and removing ice crystals
IPC: A23K10/24
Filed: 1977-01-07
Abstract: In the continuous prodn. of an albumin concentrate from aq. solns., e.g. of blood concentrate from blood, the aq. soln. is first sterilised by electromagnetic and/or corpuscular radiation.

Patent DE-2735703-A1 (DE)
Title: Flame resistant electric cable - with shrink layer between silicone rubber insulating layer and outer metal layer
Inventor: NIELSEN NIELS HENRIK
IPC: H01B7/295
Filed: 1977-08-08
Abstract: Flame-resistant electric cable comprises >=1 conductor each surrounded by an insulating layer a further insulating layer of silicone rubber, and an outer metal layer for holding in the power ash which forms on decomposition of the silicone rubber. Between the silicone rubber layer and the metal layer is a shrink layer pref. of crepe paper on cotton threads of which the vol. decreases to the same extent as the vol. of the silicone rubber increases on turning to ash. This reduces the risk of short-circuits by providing room for the expansion of the silicone rubber. Tests showed that an o.d. of 8mm of the silicone rubber corresponds to a single layer of crepe paper of 50 g/m2.

Title: Flat paper prods. stacking machine - has travelling lifting frame with horizontal stacking plate sliding sideways
Inventor: BRENNER HERMANN
IPC: B65G57/10
Filed: 1977-12-24
Abstract: The machine stacks flat items assembled into layers or blocks on pallets etc. and is esp. for semi-finished and finished products of the paper-processing industry.
